4.4 Managing Climate Change

Question 1

How can alternative energy production manage climate change?

Answer 1

➢ These alternative sources don’t emit carbon dioxide, so it doesn’t contribute to the enhanced greenhouse effect

Question 2

What is carbon capture?

Answer 2

➢ It is a type of technology that can capture CO2 produced from the use of fossil fuels in electricity generation

Question 3

How does carbon capture work?

Answer 3

➢ Once captured the carbon gas is compressed and transported by pipeline to an injection well
➢ Then it is injected as a liquid into the ground to be stored in suitable geological reservoirs

Question 4

How can planting trees help manage climate change?

Answer 4

➢ Trees act as carbon skins, removing CO2 from the atmosphere
➢ They also release moisture into the atmosphere.
➢ This has a cooling effect by producing more clouds, therefore reducing incoming solar radiation
